demand function

demand function

a form of notation that links the DEPENDENT VARIABLE, quantity demanded (Qd), with various INDEPENDENT VARIABLES that determine quantity demanded such as product price (P), income (Y), prices of substitute products (Ps), advertising (A), etc.:

Changes in any of these independent variables will affect quantity demanded, and if we wish to investigate the particular effect of any one of these variables upon quantity demanded, then we could (conceptually) hold the influence of the other independent variables constant (CETERIS PARIBUS), whilst we focus upon the particular effects of that independent variable. See DEMAND CURVE, DEMAND CURVE ( SHIFT IN).
